                AFCO continues the commitment to bring new and  innovative components to the racing community. Pillar vane brake rotors are  engineered to provide superior strength, reduce rotor weight and run  cooler. At the heart of the rotor, each pillar is diamond shaped  providing brake pad surface stability as well as reducing rotating  weight over rotors of similar strength. Racers will take note of reduced  weight when compared to rotors of similar strength. Reduced rotating  weight means reduced lap times. When brake performance is discussed,  AFCO is the bottom line.

    • Machined and double disc ground to assure precise flatness
    • Precise pillar placement for high volume cooling
    • Premium center - split castings reduce stress risers
    • Rotationally machined balanced - CNC
    • More brake pad surface support (pillars) to prevent rotor cupping
    • Strength of an 80 vane rotor with the weight savings of a 32 vane rotor

                Wilwood's 3 hole mount rotors are precision CNC machined from high strength billet plate. Full symmetrical machining provides perfect balance, perfect flatness and the truest rotation of any rotor being built. These rotors fit the popular 3 x 5.00" mount bolt circle found on most sprint and midget front hubs. Wilwoods engineered drill slot pattern combines the highest degree of weight reduction with the highest resistance to thermal distortion in the contact faces. You get smooth engagement and a consistent full pedal from the low knock-back characteristics of this design. A durable black anodized finish prevents corrosion and simplifies the visual inspection of the contact faces. The best results are always achieved using PolyMatrix Q compound brake pads with these rotors.

    Every Wilwood brake rotor is cast from premium grade, long grain carbon iron. This material exhibits long wear, high thermal stability, and excellent resistance to distortion in high heat. Modern foundry and machining techniques hold close tolerances on face and vane thickness. Combining the correct face thickness with a 32 vane casting provides superior heat management and long service life with low rotating and unsprung weight. The straight vane design also makes it possible to use the same rotor on left or right hand mounting locations.

    Steel rotors have applications in all types of motorsports. Steel rotors provide a durable lightweight option in applications where sustained temperatures remain in the low to moderate range, and high heat spikes are only observed on an intermittent basis. This could be anything from a hard stopping drag race car at the end of a quarter mile, or a high speed stock car coming in from a qualifier at a super speedway. Steel rotors can also be found in lighter weight open wheel cars such as sprints and modifieds, and a variety of light weight, open wheel road course racers. A special alloy and proprietary manufacturing processes give these rotors high resistance to thermal distortion with excellent friction and wear characteristics against the pads.

    • 10-3/4" diameter

                AFCO's new “Pillar Vane” Hybrid hub and rotor program are targeted at Circle Track racing, Open Wheel Modified, Street Stock, Hobby Stock and related classes.  The new hybrid rotor combines the strength of Afco's 1975-’81 Ford style hub with the lighter design of a GM Metric rotor. The “Pillar Vane” rotor technology produces lightest, coolest running and strongest hub and rotor assembly in the industry.

    This new rotor will improve strength, improve cooling, reduce un-sprung weight, reduce vibration, improve traction and increase driver feel and overall brake system performance.
    • Pillar Vane design promotes improved pad surface support – no cupping
    • Machine balanced to reduce vibration – improved traction
    • Double disc ground for precise flatness
    • Improved brake system cooling through usage of pillar design
    • Lightest Hybrid rotor-hub assembly on the market
    • Available in flat design
    • Proven by top chassis builders and racers Nationwide
    • 5/8" Coarse Studs on 5" x 5" Pattern

    Proper Break-In Procedure for Steel or Cast Iron Rotors:

    New steel/iron rotors should be bedded in before being used in racing conditions. Proper bedding will prepare the rotor surface, prolong the rotor's life, and make it more resistant to thermal checking or cracking under severe braking conditions. The

    Wilwood's GT 48 Curved Vane Spec-37 rotors are manufactured from a proprietary iron alloy developed to withstand extreme temperatures with the highest possible degree of resistance against distortion, warping, cracking, and wear. The formulation for this alloy is a derivative of technology and materials that were significant in the development of the extreme duty military spec rotors that are manufactured by Wilwood. Every Spec 37 rotor is precision machined to less than .001" run-out, flatness, and parallelism. Combined with the proven GT Series asymmetrical face slot pattern and individual dynamic balancing, you are assured the smoothest, vibration free performance at any speed. These rotors provide the highest cooling capacity and longest service life for extreme braking short tracks and road course competition.

                Wilwood's Drilled Steel brake rotors provide a durable lightweight option in applications where sustained temperatures remain in the low to moderate range, and high heat spikes are only observed on an intermittent basis. Steel rotors are typically found in lighter weight open wheel cars such as sprints and modifieds. A special alloy and proprietary manufacturing processes give these rotors high resistance to thermal distortion with excellent friction and wear characteristics against the pads.
